  • FEMCON Fe is indicated for the prevention of pregnancy in women who elect to use this product as a method of contraception.

    Oral contraceptives are highly effective. Table 2 lists the typical unintended pregnancy rates for users of combination oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, the IUD, and implants, depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates.

    ChanceThe percentage of women becoming pregnant noted in columns (2) and (3) are based on data from populations where contraception is not used and from women who cease using contraception in order to become pregnant. Among such populations, about 89% became pregnant in one year. This estimate was lowered slightly (to 85%) to represent the percentage that would become pregnant within one year among women now relying on reversible methods of contraception if they abandon contraception altogether8585
